What is the difference between antigenic and phase variation?
MayaChoudry
The Phase Variation is the reversible ability of some bacteria to turn an and off the expression of genes coding for the surface antigens .
While the Antigenic Variation is the modification of the gene for an expressed surface antigen by genetic recombination with one of many variable unexpressed DNA sequences.
In this manner , the expressed surface antigen can assume many different antigenic structures

What is different between analysis phase and synthesis phase?
synthesis phase synthesises while analysis phase analyses
How does meiosis introduce genetic variation into offspring?
1 by crossing over in prophase I , 2 by independent assoartment and 3 by mutations in s phase .1 by crossing over in prophase I , 2 by independent assoartment and 3 by mutations in s phase .Meiosis produces variation in gametes by crossing over & independent assortment also called reshuffling of genetic material . Such gametes after fertilization produce offspring with different characters .
What is the relationship between DNA replication and the s phase of the cell cycle?
The S phase is the DNA Synthesis phase, when the number of chromatids doubles.
Fill in the blank The G0 phase can occur before the phase?
The G phase of the cell cycle is split into two sub-phases: the G1 and G2 phases. In between these two phases is the S phase (the synthesis phase). One can say the G phase (or the first of the two G sub-phases) occurs before the S phase.
What is the phase between cell division?
In simplier form it occurs in the Interphase.
What is the importance of phase variation in bacteria?
Phase variation in bacteria allows for rapid adaptation to changing environments by altering surface structures or gene expression. This can help bacteria evade the host immune response, colonize different niches, or switch between different forms of growth or pathogenicity. Understanding phase variation is important for developing effective strategies to combat bacterial infections.
What is the relation between the path difference and phase difference?
Relation between phase difference and path difference is path difference/wavelength=phase difference/2*pi
Is there a difference between three phase and single phase electrical supplies?
Yes, there a difference between three phase and single phase electrical supply services.
How do you measure phase difference between 2 pendulums?
You can measure the phase difference between 2 pendulums by measuring the distance between the two. The amount it comes out to will be the difference.
What is the difference between cw and steady at lock-on phase?
What is the difference between cw and steady at lock-on phase? I don't know.
What is difference between a phase and a phase transition?
a phase is a region with homogeneous (uniform) properties and a conversion between states is called a "phase transition"
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
What is the difference between nano anatase and nano rutile?
Nano anatase and nano rutile are both forms of titanium dioxide nanoparticles, but they have different crystal structures. Anatase has a tetragonal structure, while rutile has a more compact orthorhombic structure. These structural differences can affect their physical and chemical properties, such as reactivity, stability, and optical properties.
What is the difference between two phase and double sampling?
Two-phase sampling involves selecting initial units from a population through one sampling technique and subsequently selecting final units from the initially drawn units using a different sampling technique. Double sampling, on the other hand, involves selecting two independent samples from the same population, where the second sample is used to check the results of the first sample and make adjustments if needed.
What is the difference between energy investment phase and energy payoff phase?

What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
What is difference between cooler and condenser?
Type your answer here... the basic difference is the phase of the material which is to be cooled i.e.in condencer it is in vapour phase & in cooler it is in liquid phase.
